#10 Add backup/restore DB file

[Steven Day]

We need to add a backup/restore file that represents a bluewave universe on file. This is different from a backend data source as it will be used to just load or save a snapshot of the objects and schema on an Bluewave level as opposed to a custom backend such as SQL, XML, CSV, etc. The backend file should be an XML file that represents one universe at a time. Permanent object types should be saved and only object types that are utilized in the universe should be backed up along with the universe. The order of a backup/restore should be as follows:

- Object Definitions
- Universe Creation
- Universe Objects
- Children Objects
- Reference Objects
